An In2O3 supported nickel catalyst has been prepared by wet chemical reduction with sodium borohydride (NaBH4) as a reducing agent for selective hydrogenation of carbon dioxide to methanol.Highly dispersed Ni species with intense Ni-In2O3 interaction and enhanced oxygen vacancies have been achieved.The highly dispersed Ni species serve as the active sites for hydrogen activation and hydrogen spillover.Abundant H adatoms are thereby generated for the oxygen vacancy creation on the In2O3 surface.The enhanced surface oxygen vacancies further lead to improved CO2 conversion.As a result,an effective synergy between the active Ni sites and surface oxygen vacancies on In2O3 causes a superior catalytic performance for CO2 hydrogenation with high methanol selectivity.Carbon monoxide is the only by product detected.The formation of methane can be ignored.When the reaction temperature is lower than 225 ℃,the selectivity of methanol is 100％.It is higher than 64％ at the temperature range between 225℃ and 275 ℃.The methanol selectivity is still higher than 54％％ at 300 ℃ with a CO2 conversion of 18.47％％ and a methanol yield of 0.55 gMeOH gcat-1 h-1 (at 5 MPa).The activity of Ni/In2O3 is higher than most of the reported In2O3-based catalysts.
